The SmartCode 916’s small size makes it less conspicuous than other locks, and allows you to use your old house keys if you want. Kwikset’s SecureScreen feature — which makes you punch in two random digits before entering your code — helps ensure burglars can’t guess your password by fingerprint smudges alone. And it has an alarm if someone tries to break in. The 916 lacks a standalone app, but can be connected to several smart home hubs via Z-wave or ZigBee. Overall, a great all-around lock that allows you to ease into the world of smart locks, “unlocking” its best features as you feel comfortable.
